Body mass of six long-distance migrant passerine species along the autumn migration route [PDF]

open access: yes, 2018
Summary: We analysed body mass and moult data of six passerine species along their autumn migration route from northern Europe to North Africa and derived hypothetical models of the organisation of their migration in terms of fuel store accumulation.

The role of a non-native forest in the stopover ecology of migratory passerines

open access: yesProceedings of the Zoological Institute RAS
During their journey, migratory birds need stopover sites where they can replenish their energy stores. Mosaic forests of agricultural areas, often planted with non-native trees, can provide opportunities for birds to do this. In the present work, I sought to answer the question of the importance of these habitats for migratory birds. For this reason I

Ecological drivers of songbird stopover behaviour during autumn migration in eastern New Brunswick [PDF]

open access: yes
As songbirds migrate, they must periodically stop to rebuild the energy needed for flight. Individual traits, local habitat characteristics, and the surrounding landscape can affect stopover refuelling and movement, yet the relative importance of endogenous and exogenous factors and the interrelation between refuelling and movement is less well ...
